1. SCREENING FOR ANTIBIOTIC RESISTANT BACTERIA IN URINE SAMPLES
Volume 1, Issue 1 , Autumn 1989

Abstract
  Chronic urinary tract infections are often caused by antibiotic resistant bacteria. In some of these cases, prediction of the most effective antibiotic (s) may urgently be needed. This can not be achieved unless the nature and patterns of the resistance to antibiotics among the pathogenic bacteria ...  Read More

Volume 1, Issue 1 , Autumn 1989

Abstract
  The activity of aspartate aminotransferase a vitamin B6 containing enzyme was measured in the laysed synaptosomes prepared from rat brain, during development. Administration of vitamin B6 increased the enzyme activity throughout development. The stimulating effect of this vitamin was prevented when ...  Read More

4. Endotoxin Contamination of Large Volume Parenterals as Detected by Limulus Amebocyte Lysate as an Alternative to Rabbit Pyrogen Test
Volume 1, Issue 1 , Autumn 1989

Abstract
  The possibility of replacing the rabbit pyrogen test by the Limulus Amebocyte lysate (LAL) test, as a final release test for Large Volume Parenterals (LVPs) was investigated. The sensitivity and specificity of the LAL test and rabbit pyrogen assay were studied by means of artificially contaminated ...  Read More

5. GRAVIMETRIC DETERMINATION OF NICKEL WITH CYCLOHEXYLIDINE-AMMONIUM-2-AMINOC YCLOHEXY LIDINE- 1-CYCLOHEXENE-1-DITHIOCARBOXYLATE
Volume 1, Issue 1 , Autumn 1989

Abstract
  Cyclohexylidine-ammonium-2-aminocyclohexyline-l-cyclohexee-l- dithiocarboxylate (CCCD) is employed for the gravimetric determination of Ni (II). In neutral or ammoniacal solutions, the metal forms a violet precipitate with the reagent which can be weighed as Ni (C13H18NS2)a2f ter drying at 115 - 120?C Using ...  Read More

6. The Synthesis of Zeolites A, X and HS from Natural Iranian Kaolinite and the Study of the Transformation of Zeolites X to HS and Zeolites Y to P by X-ray diffraction and Scanning Electron Microscopy.
Volume 1, Issue 1 , Autumn 1989

Abstract
  Zeolites A, X and HS were synthesized from natural Iranian Kaolinite by alkaline fusion,,followed by refluxing the mixture. The transformation of zeolites X to HS and Y to P were studied at different time intervals by X-ray diffraction and Scanning Electron Microscopy (SEM). It was revealed that in ...  Read More

7. Photochemical Rearrangement of 8- methyl Spiro [2.5] oct-7-en-4-one to 4-methyl Spiro [2.5] oct-4-en-6-one
Volume 1, Issue 1 , Autumn 1989

Abstract
  Irradiation of &methyl spiro [2.5] oct-7-en-4-one through its singlet excited state resulted in the formation of 4-methyl spirO [2.5] oct-4-en -6-one. We have used the cyclopropyl moiety in the molecule as a probe to study the operating mechanism in the photochemistry of ?, ?-unsaturated compounds. ...  Read More

8. A General Method for Selective Tritylation of Primary Hydroxyl Groups in Carbohydrates and Related Compounds
Volume 1, Issue 1 , Autumn 1989

Abstract
  A general and rapid procedure is developed for the selective tritylation of the 'primary OH-function of the four common ribonucleosides, ascorbic acid, and polyhydric compounds. Silver ion was found to have a marked effect on tritylation reactions  Read More

10. SYNTHESIS AND ELECTRONIC ABSORPTION SPECTRA OF SOME METHOXY HALF-ANALOGUE OF MICHLER'S HYDROL BLUE
Volume 1, Issue 1 , Autumn 1989

Abstract
  The present work comprises the synthesis of one series of diarylmethane dyes containing one or more terminal methoxy substituents together with a variable tertiary amino group. The electronic absorption spectra of the dyes have been determined. As the conjugation of the terminal nitrogen atom improves ...  Read More
